Abstract

The influence of light intensity on growth and biochemical constituents of two species of Spirulina; Spirulina platensis and Spirulina fusiformis was studied. Various light intensities of 1000, 1500, 2000 and 2500 lux were investigated. The best growth for both S. platensis and S. fusiformis were found at the intensity of 2500 lux and at 1000 lux both species showed slower growth. The results indicated that at highest light intensity the protein content increased while the carbohydrate and lipid content decreased. Maximum protein content of 59.2 % and 60.6% were found at 2500 lux for 5. platensis and S.fusiformis respectively. Maximum biomass productions were also achieved at 2500 lux for both the species and they were 2.1 and 2.2 g/1 for S. platensis and S. fusiformis respectively. Carbohydrate and lipid content was high at 1000 lux for both the species. Phycocyanin and carotenoid content was found higher at optimal light intensity of 2500 lux.
